The National Weather Service has issued a severe thunderstorm watch.
Boise faces severe thunderstorms with possible tornadoes, large hail and wind gusts up to 70 mph, weather officials warn. Residents across the Boise area are being urged to prepare for dangerous weather conditions as forecasters warn that severe thunderstorms could bring destructive winds, large hail and even isolated tornadoes to parts of southwest Idaho.
The National Weather Service issued a severe thunderstorm warning Thursday for portions of the Treasure Valley as storm systems intensified across the region.
Meteorologists said strong thunderstorms are expected to move through Ada County and surrounding areas throughout the day, bringing the potential for rapidly changing and hazardous weather conditions.
Severe thunderstorms threaten southwest Idaho
Weather officials warned that some storms could become especially intense as winds strengthen across southwest Idaho.
According to forecasters, wind gusts could reach up to 70 mph in certain areas, creating the possibility of downed tree branches, flying debris and dangerous travel conditions.
Forecasters warned of possible tornado development in isolated areas. Large hail measuring roughly the size of ping pong balls could accompany stronger storms, heavy rain and blowing dust may reduce visibility for drivers across the region.
The National Weather Service also said thunderstorms may produce brief periods of intense rainfall capable of quickly flooding roadways and low-lying areas.
Images shared throughout the day showed dark storm clouds forming above Boise as weather conditions deteriorated across parts of the Treasure Valley.
Severe thunderstorm watch issued for multiple counties
The National Weather Service placed several Idaho counties under a severe thunderstorm watch through Thursday afternoon.
The watch included Ada County along with portions of Canyon, Owyhee and Elmore counties.
Officials also issued a special weather statement for the Treasure Valley as forecasters monitored the potential for rapidly intensifying storms.
Emergency officials warned residents that strong winds could blow unsecured outdoor objects across neighborhoods and roadways.
Blowing dust was also expected to create visibility concerns for motorists, especially on open highways and rural roads.
Idaho residents urged to prepare now
State emergency officials encouraged residents to take precautions before weather conditions worsen. People were advised to move indoors into sturdy buildings away from windows and doors during storms. Residents were encouraged to secure outdoor furniture and loose objects before high winds arrive.
Drivers were urged to avoid flooded roads and use caution during heavy rain or blowing dust.
Emergency management officials also advised residents to avoid using electronics or running water during periods of frequent lightning activity.
Travelers caught on the road during severe weather were told to pull over in a safe location if conditions become too dangerous to continue driving.
Officials stressed that flooded roadways can quickly become deadly during strong thunderstorms.
According to Idaho emergency management guidance, even a small amount of floodwater can stall vehicles, while deeper water can sweep cars away entirely.
Tornado risk adds unusual concern
Although tornadoes remain relatively uncommon in Idaho compared with other parts of the country, forecasters said atmospheric conditions Thursday could support isolated tornado development.
The possibility of tornadoes added another layer of concern to an already dangerous weather setup.
Photos shared by weather officials from previous years highlighted rare tornado activity previously captured near Pocatello, reminding residents that twisters can occur in the state under the right conditions.
Meteorologists emphasized that not every thunderstorm would become severe, but they warned that any storm capable of producing rotating winds should be treated seriously.
Storm activity expected beyond Boise
The severe weather threat was not limited to Boise alone.
Forecasters also warned that portions of western Idaho and the state’s northern panhandle could experience strong to severe thunderstorms later Thursday.
Areas near Grangeville and Lewiston were identified as regions with an elevated risk for damaging winds and large hail.
As storm systems continue moving across Idaho, officials encouraged residents to stay alert for updated watches and warnings throughout the day.
Weather experts said conditions could change rapidly depending on how individual storm cells develop.
For many residents across southwest Idaho, Thursday’s forecast served as a reminder that severe spring weather can quickly create dangerous conditions even in areas where tornadoes are relatively rare.
